ZLBGL系列袋式过滤器主要适用于液体精密过滤。具有过滤精度高、处理量大、成本低廉、使用维护方便等特点。其内部由金属网篮支撑过滤袋，需要过滤的液体从进液口流进，经过滤袋过滤后，大于过滤孔径的杂质被拦截于滤袋的深层及内表面，滤液透过滤网汇聚于出液口流出。选择不同的过滤袋可以达到不同的过滤精度，过滤袋可以实现快速更换或经冲洗后重复使用。

      ZLBGL series bag filter is mainly used in liquid secondary filter, with such features as higher filtering precision and processing load but lower cost and easy operation and maintenance. It has metal net to support the filtering bag inside, with liquid to be filtered getting in from inlet. After filtered with filtering bag, impurities larger than the filtering hole diameter are intercepted onto the greater depth and inner surface of the filtering bag. Filtrate is collected at the outlet through filtering bag before being discharged. Choosing different filtering bags can reach different filtering precisions. Filtering bags can achieve faster replacement or are reused after flushing.
